Raydium 3D Game Engine

Hi, I have seen Mania Drive is a little bit difficult for children. I made couple of modifications to test is game then funnier to children. Patch is also for starting discussion about 'kidsmode' / trainer / cheat-mode...

a) all story-tracks are always playable
b) Acceleration and top-speed can be tuned before start track

I didn't find what file can be attachment, so here it is:
